What to buy with your estimate
Your resin amount is only part of the setup. Most failed beginner projects come from missing cups, gloves, stir sticks, pigments, or a bubble-removal tool.

- Do not start with a giant table pour. Practice on coasters, trays, or small molds first.
- Check the maximum pour depth. Deep-pour resin and tabletop resin are not the same thing.
- Measure by the product instructions, not by vibes. Ratio mistakes ruin the cure.
- Plan for overflow, drips, and test pours. A 10-15% buffer is normal.
